1. With ulka vibratory pumps the E series is the high pressure series. 5 is the flow curve, so you should see nearly identical flow with each of those pumps. This can be seen on the Spec sheet for the E series pumps. <http://files.cemegroup.com/elettropompe/0/60/Scheda%20tecnica%20E%20high%20pressure.pdf?v=636869779789441307> The biggest difference on all of these is the duty cycle, and the materials. The EAX pump is plastic, while the EX and EFX is brass. The duty cycle (the amount of time it can run/the amount of time it needs to rest in minutes) is 1/1.5 for the EAX, 1/1for the EX (at 120VAC) and the EFX is 2/1 (same for the EX @220VAC). So basically the EAX is the least durable, while the EFX is the most durable. Unless you are considering something like flow profiling there is no reason to get the EFX over the EX, but the EAX is plastic with a much lower duty cycle, so should probably be avoided for this application.
